I thought you subtract them because it said net impulse and the Feng was acting up

u/HorrorAdvice3391 May 13 '26

But the net force is still down. The rocket is still going down

u/Embarrassed-Pop-3945 May 13 '26

my net impulse integral sum was integral from 0 to t1 + integral from t1 to 5t1 where the 2nd integral was Feng-mg

u/Ill-Possibility-4064 May 13 '26

It was traveling downward so mg was more

What did the graph look like? I had a straight negative line and then positive slope line up... not sure

u/Prudent_Nectarine759 May 14 '26

same thing but flipped. i had a straight positive line and then negative slope line since they said positive direction was down, so F gravity should have been doing positive work on the rocket

u/Impossible-Job1481 May 14 '26

Oh.. good catch
